What's Required in Austin

  • No permit required for detached one-story structures 200 square feet or less and under 15 feet in height.
  • Structures over 200 square feet or those including electrical, plumbing, or mechanical work require a building permit.
  • Must maintain a minimum 5-foot side yard setback and 10-foot rear yard setback in SF-2 standard zones.
  • Maximum lot coverage and impervious cover limits (typically 40% and 45% respectively) must not be exceeded.
  • Any foundation exceeding a standard portable base may trigger a structural review and permit requirement.
  • Placement within a public utility easement or the front yard setback is strictly prohibited.

What Size Shed Needs a Permit in Austin

Whether you need a building permit for a shed in Austin usually comes down to size. In Austin, the cutoff is clear: detached sheds of 200 square feet or less don’t need a building permit, while anything larger does. A popular 10x12 shed (120 sq ft) comes in under the limit, so it typically doesn’t need a building permit. Larger sheds, and any shed with electrical, plumbing, or a permanent foundation, almost always need a permit regardless of footprint.

Building a Shed Without a Permit in Austin

Even when a shed is small enough to skip a building permit in Austin, “no permit” doesn’t mean “no rules.” A permit-exempt shed generally must stay at or under the 200-square-foot limit, sit on a non-permanent base (sheds on skids or a gravel pad are treated more leniently than those on a poured foundation), and have no electrical or plumbing run to it. Crucially, zoning setbacks still apply — your shed usually has to sit a minimum distance from property lines and other structures, and that holds even for a permit-free shed. Confirm both the size exemption and the setback distance with the City of Austin Development Services Department before you build.

Frequently Asked Questions

No, a 120 sq ft shed is under the 200 sq ft threshold and does not require a permit if it has no utilities and is under 15 feet tall.
Typically, you must maintain a 5-foot side setback and a 10-foot rear setback in common SF-2 residential zones.
No, any structure with electrical wiring requires a permit regardless of its size or height.
In Austin, sheds of 200 square feet or less can be built without a building permit; anything larger needs one. The exemption usually also requires no permanent foundation and no electrical or plumbing, and zoning setbacks from property lines still apply even without a permit.
Often not, if it’s also within Austin’s 200 sq ft limit and has no utilities — many jurisdictions treat a shed on skids or a gravel pad as movable rather than a permanent building. A poured foundation or any electrical/plumbing typically triggers a permit. Confirm with the City of Austin Development Services Department; zoning setbacks apply either way.
